Kinda figured you would sum them up concisely in a small nut shell. Had the door locked in case you hurled the hammer from Utah.

Positively infinitely variable gearbox. Many with smooth chain and smooth sheaves. strange Blitzkrieg your mind by the Germanic folks. I maintained a carding machine with 19 PIV's. another bizarre machine. PIV: This is a single cylinder card. Our machine had 4 drums in series. The drums and rollers are basically wrapped with band saw blades, teeth facing outward. Carding wire, sharp old wool 3 cylinder

Carding wire, sharp old wool 3 cylinder seems to me they tried to use those in cars back in the 1980's or so and they couldn't handle the power. How many horsepower your they subjected too in the carding machines?

Had to fix a PIV type spindle speed control on a Bridgeport mill once, lotsa fun. There are a few new cars recently revisiting the concept, still not working out so well but if they can figure it out it should improve fuel economy immensely.

[/url][/quote] The carding machine had a 40 HP main motor. And the other 18 PIV's were mostly driven off that motor with a bunch of cross shafts under the machine. Seemed like the PIV liked to operate with a lot of constant torque at medium speeds. To tear polyester fiber and orient it the way it did took a bunch of torque. it was made in Germany by Hergeth/Hollinsworth. Never broke down, ran like a top. We had to tear it down and replace the wire on about all the rolls once in a while when a foreign object got caught in it. Usually a lamb's leg when running wool where the shearer got to aggressive with the lamb shears-go figure. That was the only way we could figure a lambs leg was in the virgin wool. It was a non-digital totally analog controlled machine using tachogenerators for signal feedback. Old school stuff. Control panel looked like something from a space ship. It fed bat to a needle loom with 3 forty foot drive shafts that maxed at 600 RPM. We had to limit it to 400-500 RPM. The vibration was a problem, adjacent subdivisions complained about the ground shaking. We poured 347 yards of concrete into the foundation of the needle loom to hold it in place. footings 25 feet deep.

Two crankshaft Feher needle loom, probably 13 meters. To make no seam press felts for paper machines. $30-100 thousand per felt.

Simple single crank shaft needle loom. loud. Fed by card. Folded by lapper. fed into needle punch machine. Sounds like 400 RPM I was in charge of keeping it running. Most of the guys are production people. Hope I never see another one of those lines.
